Application led December This invention yrelates to sash-fasteners,

and has for its object the provision of. etlicient means adaptedr to be applied to the upper and lower sashesof a window for locking them together in their 'fully closed positions, and also in positions to afford openings at the top' and-bottom oi awindow Jor the purpose of ventilation.

rlhe invention consists in the novel construction, arrangement and combination of parts hereinafter described and claimed. ln the accompanying drawing, Figure 1 is a perspective vview ot one side of a windowvframe, and oportions of the window sashes provided withV fasteners cmbodying my invention. Fig; 2 is a vertical transverse sectional view oi? Fig. 1.y 3 is a horizontal section yon line 3 3 or Fig. 2. l

In said drawing, the reference p nun'ieral "3 represents a side member ot a window cas-` -ing provided with ways 6 and 7 for they side rails 8 and 9 of the upper and lower wincow sashes, respectively.

Secured as by means of screws 10 to the side rail 8 of the upper sash is a vertically disposed metal bar or strip llhaving cen-fv trally of its width, a series of recesses 12 .vhich are ar1an,g,ed in spaced apart rela- Vtions longitudinally of the strip. Said recesses are o'' less width than the Y strip and of substantially rectangular shape in iront elevation to provide ver ai bar elements 13 at'opposite sides of the recesses and horizontal bar elements 14 between th, successive recesses.

Cooperating with'said strip is a instal latch which is indicated, generally, by 15. Said latch is formed to provide two arms 1G and 17 arranged in angular relation with eachother, the extremities 18 an 19 oi the respective` arms being of a width, to permit their entering the strip recesses 12. Y

Said arm extremities are, moreover, spaced vertically apart so as to be simul taneously engageable against the under and upper surfaces, respectively, of horizontal bars 1d of-the strip 11. The latch 15 is mounted 'iorrotary movement uponjfa base lplate 20 which is rigidly secured upon the .top of the parting rail 21 of the lower sash by suitable means such, for example,V asscrews 22. y

As shown, the latch arm 17 is seated upon v1952.5.` serial No. 74,271,

the plate l20 and is connectedthereto inoffset relation with the strip 11 by means of av pivot pin 23 eXtendingthrough both thev arm 17V and said plate.

By thus pivotally connecting the latch to the plate, the latch is capable ot being swung about a vertical axis into and troni its locking position, as represented by full lines in the drawing, with respect to the strip upon the upper sash the sashes together.

To disengagel the thereby coupling sashes with respect to each other, the latch is swung-into the po-1 sition inwhich it is represented. bydotted lines 151 in Fig. '3.

For the purpose of safeguarding the latch from being tampered with by a thin instrument inserted between the sashes from l the outside vot the window, I' provide the base plate with a catch device 'for retaining vthe latch in its engaged position. To such nd, the base. plate 20 is slotted transversely at 25 to provide ay tongue 26 having a protuberance 27 adapted to. engage Vagainst a side of the latch arm 17 to hold the latch in its engaged position. To re-1 lease the latch i'or permitting the sameto bc swung out of engagement with the strip, the protuberance 27 is iorced down out of the wayA ci the sash by a pressure of a perf latch into .engagenaent within recesses rof the strip. rlhis may be done when the window is closed or when partly open. lVhen the sashes inpartly open positions are coupled by my Yliastenergthe two sashesare movs able togetherup or down to ailord draft for Ventilating purposes at the top and bot-L tom of the window opening.

lhat l claim, is,. y y A sash-fastener comprising a strip member provided with a series of recesses, and means to securesaidplateto the side rail of an upper sash, a plate member adapted to bey secured to the parting rail of the lower sash, said plate being slotted to provide a tongue element therefor, a latch member mounted upon said plate, said latch being` formed of a plate folded upon itself to pro-` vide two arm elements adapted fol' engagement in s aced apart recesses ot' the strip, a means or pvotally connecting the latch to said plate to turn about an axis in laterally offset relation with the strip whereby the latch is capable of being swung into and out of engaged relations with said strip,A

and a catch provided upon the tongue element of said plate for securing the latch in its engaged position and adaptedto be disengaged from the latch by depressing said ARTHUR R. GLIDDEN.
